rlhe present inventionV relates to lsanitary basins designed'for use-in connection with wash bowls, and has for'its purpose to provide a basin of 'such construction and so adapted to the usual wash bowl, that it can bejmade and dispensed at a Aprice that will Ypermit the single use and discarding of it, so as to ensure lsanitary lavatory Conditions in public toilet rooms. 1

The use in hotels, public, and semi-public places ofthe same wash bowl by a large number of persons, is frequently the cause of the spread of slrin and other diseases. Travelers have often experienced annoyanceand dis- 'l Comfort because it is necessary to use a basin previously used by others and which obviouslyhas not been thoroughly cleansed. Moreover, in many states, laws have been enacted forbidding theuse in trains, public comfort s stations, and the like, of the samebasinlby more than one person.` In my Patent 1,538,016', granted May 19, 1925, there is shown a sanitary wash basinadapted for use with a suitable supportadapted to clamp its margin as disclosed therein, a support of this type being-disclosed in my Patent 1,499,495,

y granted July 1, 1924.

.Anobject of the present invention is to prov vide assanitary wash basin which, after use,

' l' may be discarded but which, if desirable, may

. be repeatedly used by the same person.`

A further object of the invention is to provide a paper receptacle adapted for such use and which has a margin `suitably stiffened to serve as a support `for the'receptacle when filled. vThe invention also contemplates the provision of a` marginal stiffening means which serves to fasten permanently the-endsv y of the pleator pleats which open up inwardly from the margin to provide the necessary concaved or dished formation. n Y,

Y, '.Theinvention alsocontempla-tes the provision of rests formed on the receptacle margin, the rests or supports-'being adapted to be deflected or bent soas to support the receptacle in such a way that a portion thereof is disposed beneath Vthe inlet spout or spouts of the basin. Moreover, the rests are preferably disposed at the ends of the receptacle and'of sufficient width to support the same throughout the greater portion of the width of the receptacle whereby to prevent tilting movement. If desired, the rests may be formedso as to engage a support in such a way as to prevent turning or sliding movement of the same. n

The foregoing and other objects of the invention, which are more closely related to detailsof construction, will be made clearer as the description proceeds in connection with certain preferred embodiments shown in the accompanying drawings, wherein:

The pleat i'n the present instance coincides with the maj orraxis of the ellipse defined by the contour of the `'blank and is formed so that whenpressure is applied to the central portion of theblank to be depressed, Aand thereby forming a dish-like receptacle. K

5 Ther provision of a single pleat which opens freely will form a suitable receptacle., However, v intheV preferred embodiment otthe in-v Yrvent'ion, shown in the drawings, an'addi- Y tional .pleat is' provided.. ,Thel additional pleat or fold 12,'.extends transversely of the blank at van angle tothe first mentioned pleat which `it intersects, preferably at substantially the center 13 of: the blank, f Thisfpleatj 1 2' coincides with the minoraxis ofthe ellipse deiined by" the contourot' the blank andat the fpoint ,ofl intersection fot the pleats is formed by' :tolding over uponitsel a portion 'of the pleat ll, asindicated inFig'ureZ.

Moreover, thefinvention contemplates afaslk tening means for the pleat'ends which will impart stiffness to the. margin of the blank Anysuitable pleatfastening and marginstiiieni-ng means may be employed.v For example, theembodiment of the inventionillustrated includes a channelelement 13 which receiveslthe edgeof theblankat the ends of the pleats andis adapted'to hold the endsro the pleats against opening when lthe blank inwardly from its marginris depressed.V lf

desired, the bottoml web of thechannel element lfmaybe 'somewhat wider than the top web` (Figfa) and mayy terminate in a downwardly curled edge 13'?, which provides a rounded portion for engagementwith the paper of the basinwhen thel latteris `flexed downwardly asfindicated :inF ig. 7, thereby minimizing thefdangerof ztearing the paper of the basin `when filled with water. The channel element may beformed from" any suitablel metallic or fibrous materia-l, andV preferably is extended around the blank Vfrom l each pleat sufficiently to impartto the margin of the blank suitable stiffness to permit l the margin to serve as asupport for the recep- "fw tacle when lilled; Although the channel ele-, V

ment illustrated extends entirely around the blank, it will be understood that it issimply desirable that thel means employed should. extend a suthcient distance to impart to they margin the rigidity necessaryto supportv the filled receptacle formed fromtheblank.` l

The blank with its means for permanentlyv fastening' the ends of theA pleat and stifening the margin to provide a 'support may vbepositioned uponanyfsuitable device adaptedto provide a restfor the Vblank margin and to permitv the central portion of.V the blanktobe y depressed to. open those portions of the` pleats disposed'in'wardly Vfrom the margin of the blank. When the bla-nk center is depressed, as shown in Figure 6, there isprovided a receptacle, the surface ofjwhich is smooth and devoid of yintersticeswhich would tend to vcollect" sedimentjand other impurities. The

pleats are comparatively loose inwardly from the blank margin so thatupon application ofthe pressure Vto the centralportionofithe blank the pleats'willopen freelythroughout substantially theirY entire length except, -of lff course, immediately 2 adjacent the ,margin where they ment. L Qbviously, the depth of the V,basin `depends are" gripped thegchannel eley .the-pleats fofgreater or less width the capacity Y,of thebasin may vbel varied.v Moreover,`

the extent and character of the' stiff'ening means mayvary in accordance with varia-tion Vin the size of the receptacle since ,the weight ofthe filled receptacle Vwill vary directly in f v lproportiontoits'sijze 4or capacity.

y disposed at the ends of thel major axis and Referring to Figure 6,. there is f shown a blank of the same general construction as that above described, butprovidedwith a plurality of :independent pleat fastening means,

such-aschannels 14, 15, the channels being being of somewhat greater extent than the other vchannels since they serve as the sustaining means `for the blank when positioned upon a support of the character hereinafter described. I Y

rllhe receptacle is intendedto be inserted Vwithin the bowl 16 of a basin 17 having a marginalportion 17 surrounding. the top of the bowl and an inlet spout 18 of conventional construction.V InY the vpresent instance, the

spout 18 is of the type formed integral withl the bowl although it will be understood that the invention contemplates association of the receptacle with a basin having inlet spouts of other .conventional forms, such as the separate faucet spouts. l

'In vertical planes offset from the bowl wall, and in thepresent instance projecting intorthe bowl area at each end ofthe bowl, is arranged a shelf or rest 19, the rests being confined to substantially the ends of the bowl cle is'disposed beneath the spout 18. For. this purpose the shelves,v as will be observed,

are arranged 'in a horizontal planebelow kthe outlet ormouth of the spoilt. Moreover, as is'apparent from-Figure 7, rthe supporting bowl is so formed relative'tothe receptacle and the rests-are so arranged within thebowl that the opposite-marginal portions 14', 15', `of theV receptacle intermediatethe rest and atthe front and rear of the bowl, are

spaced inwardly from the bowl' wall whereby to provide the Vspaces 20 through which an overflow from the receptacle may 4pass downwardly into the'bowl and be discharged therefrom fromY the usualdrain opening 21. As

will be observed, the rests or supports, al-

though' of less extent than the-bowl circumf ference, are nevertheless-of sufficient width to" engage :the collapsible basin margin throughout the greaterportion ofthe width ofthe basin, thereby effectively. resisting Atilting movement and also preventing bending Vof the basinv when filled with water.

v `the receptacle fis disposed within the bowl kwith its stienedmargin bearing upon thefrests19 a pressure upon` the central portion of the blank will depress and dish the blank 4by opening the pleats. Thereafter water may be introduced into the receptacle thusv formed, through the spout 18 and, as explained, any overflow during the filling of the receptacle, or as the same is used, will pass downwardly into the bowl through spaces 2O at the front and rear of the bowl. lIn order to resist sliding movement of the receptacle upon the rests 19, the latter and the receptacle margins may be formed with suitable means adapted to interengage. For example, the channel member 13, may be stamped out to provide tits 211 to project into cups or sockets in the top surfaces of the rests.

Since the receptacle is formed with a sticned margin which will support the same as described, it is unnecessary to provide a rest which will clamp the margin of the receptacle or hold the pleats against opening. Moreover, since the blank is flat as distinguished from the blank having the angularly deflected margin of my patent, the same may be more conveniently packed in transportation and readily stacked for dispensing.

Furthermore, it will be understood that although the blank shown in the drawing is of elliptical contour, this is not an essential feature of the invention since it may be made round orrectangular, or'of any other design.

Referring to Figures 9 and 10, 25 indicates a bowl of any preferred design having the vslab 26 and the usual'fixtures 37 conventionally illustrated.

The individual basin I is indicated at 28, and, as shown, will preferably follow generally vthe contour of the bowl 25, although of smalle-r diameter than the bowl, so as to leave l an overfiow area between the wall of the bowl 25 and the edge of the basin 28 at the front and rear of the basin between its ends.

The basin 28 will be formed of a thin light material, here shown of fibrous material, such as, paper, andwhere the material used, such as paper, can be readily folded, the blank forming the basin may be folded along the lines29, so that, as produced, ready for use, 'it will be flat and capable of being distendedV tobasin-like form by pressing it centrally tocause thefolds or creases 291:0 open and distend the material into a rounded basin shape. Such a construction isrdescribed in detail in my Patent No. 1,538,016, granted May 19, 1925. In4 order to give the basin stability and make it self-supporting, its edge may be stiifened in various ways, one convenient form of providing the stiened edge. where ythe basin is made of fibrous material, such as paperbeing to secure. to that edge a Vthin metal rim formed of folded and properly crimped material such as metal, as

shown in the detail views, Figures 13 and 14. Preferably, the lower ply of the metal rim 30 v Anotherwayfin Ywh-ichlfthis result mayl 'bev will be wider thanthe upper ply and :have its. edge bent slightly, as at 31, so as tozforrn a roundedcontact surfaceforthel paper basinA 28 whenin distended position, thus eliminat- 4Ving any danger of cutting ortearing' tlie paper against the edge of the-lowerrply of the Theresia es Wint@ provided esiliati@ points in its periphery with projections or `offsets 32,` two diametrically' opposedV offsets beingy here'shown for .purposesfof illustration, although suchv offsets may be greater 1n numberjand.differently disposed if desired. Where the form `of the invention embodies a paper basin and the metal. rim isy adopted, these projections 32 will-extendv outwardly from therim, and willfprefera'bly be formed integrally with the rim forwthe purposes Y y o'f'convenience in manufacture: VThese voff sets should cover` a considerable area, 'as shown,or V1n other words, be of considerable width so as topreventfforward or rearward tilting of the paperV basin, which would be possible if thejprojectio'ns were'narrow 0r pintle-lilre in' design. Preferably these proections should -besubstantially greater than one-.half the width of the paper basin, as illustrated;y Y 1 Y The purpose ofthe projections or offsets 32' Vis to `support the basin, asshown in Figures 9 and 10, 'upon the slabQ, andin theusual fixture the basin will beso disposed Ywhen in place` that it will :lie below the level ofthe. outlets of thefixtures 27 and extend beneath lthem farenough tojreceive water therefrom..

Where it is necessary to,l drop theindividual basin deeper inthe bowl inorder tobring it ybelow the level of Athe water outlets, which yinVFig-ures 14 and-15, where theprojections i Vmight be thecase where the outlet is formed in thewallV ofthe basin, thevprojections on the/rim ofthev Ybasin may be formed as shown 33' are bent upwardly'and vthen outwardly from the rim so. as to give Va supporting lip '.34 .to rest upon ythe slab, .therebydropping .fthebasin deeperinto the bowl and bringing it below the level of the water outlets.

1 Viith an individual basin lof thislcharacter, which-is, of course-very light, but sufficiently i strong to Vserve the needs of an individual user, it is desirable tozprevent accidental shifting or movement of the b'asinon the'slab while 'in'.u'se. This' may be accomplishedin vvarious ways, as, for example, by providingV seats 35, as shown in 4Figures 9 vand 10, vin the top ofthe slab at theproper'points to receive the projections '32 orV 34Y on the basin,

` and these seats 35 may be readilyformed` in the yslab. and of such design and character 'as' j not to" affect inany way the'appearance of the slab orproduce unsightlyor unsanitary crevices.

Y 'f e L v- While thisis a` convenient; and practical form-of the device, there is shown inFigure 16 a `construction. which flends Vitself to use with ythat form of basin in which theprojecs tions on the basin are notoffsetg, butare ofthe form Vshown in Figures 9 and 10. YIn this form of the invention,where there is pro-V vided a basin spoutk 39, below the top of the slab onthe innerwall of thebowl, the `seats .40 will be 'made deep enough vto permit the supporting projections 41 to drop down to the inclined bottomj42 .which is at a .level bringinv the basin below the inlet'Y spout 39,v

so that whichever form o'fwash bowl is Vprovidd, the straighteedgev type basin'rm'ay be use. f-

As shown in Figure 17, that forinof the invention inrwhich the supporting projections 44 are offset may be'rused, if desired, by simply reversing it, as shown, so thatthe offset projections 44 forin'supporti-ng feet,

ends, when the basinv is arranged in the bowl,

as illustrated in Figure 9. Although the projections yare describedy as being ofvconsiderable width, it' .will be vunderstood that the underlying idea'isxto arrange them so that ,they support the basin throughout a condesired, either to the shape shown in Figure 15 Lor tothe shape shown in Figure 17 or to any other shape which may be preferable for the purpose of adapting the basin rests to the particular support for which 'they are to be employed.

, The advantages of the invention disclosed are that an individual wash basin is provided vwhich may be dispensed at smallcost to the public and provide each user with a sanitary device, which, after Once being used, may be thrown away, although it will be understood that the make-up ofthe individual basin is such that it is capable,in the hands of the individual user, of a very considerable use without deterioration. It is intended, however, that where such basins are dispensed, e1-

ther by attendants in toilet rooms, or through vending machines, by which the basin may be very readily handled, there shall be no coininon'use of the basin by the public, and thus Y kthe danger of'contamination by promiscuous use of wash bowls in public paces is eliminated. The construction lends itself to rapid and cheap production, so that the basin may be turned out in large numbers and sold to the public at reasonable cost.

Although I have referred throughout the specification and claims' to the basin as being formed of paper, it will be understood that this term is used in a broad sense to cover any paper-like material of flexible character requiring a stiffening supporting` medium along its edge. y

As stated, the disclosure here is illustrative, and such variations from the particular dis*y closure as are within the skill of the mechanic "may be made without vdeparting from the range of my-invention.
